eDPI Explained: Find Your Perfect Gaming Sensitivity

If you have ever wondered why your aim feels inconsistent between games, the answer is usually eDPI. Effective DPI (eDPI) is the single metric that unifies your mouse hardware settings with your in-game sensitivity into one comparable number. This guide explains how to calculate it, what ranges work for different games, and how to calibrate your perfect sensitivity.

What Is eDPI?

eDPI stands for effective Dots Per Inch. It is the product of your mouse hardware DPI and your in-game sensitivity value:

For example, if your mouse is set to 800 DPI and your Valorant sensitivity is 0.35:

A player with 1600 DPI and 0.175 sensitivity has the exact same eDPI (280) and therefore the exact same physical 360° turn distance. The DPI setting only matters for how the mouse hardware reports motion; the game engine normalizes it through eDPI.

Why eDPI Is the Only Metric That Matters

Raw DPI and in-game sensitivity values are misleading in isolation. Two players with different DPI settings can have identical aim when their eDPI matches. eDPI is alsonot comparable across games — each game engine interprets sensitivity differently, so 400 eDPI in CS2 ≠ 400 eDPI in Valorant.

The universal metric that does work across all games is cm/360 — the physical distance (in centimeters) you must move your mouse to complete a full 360° rotation on screen.

Recommended eDPI Ranges by Game

These ranges represent competitive play at 800 DPI. Lower eDPI means more physical movement for precision; higher eDPI means faster turns but harder micro-adjustments.

Note: Fortnite and Overwatch 2 use different internal sensitivity scales, so their eDPI numbers are not directly comparable to CS2 or Valorant.

cm/360: The Universal Metric

cm/360 measures the physical mouse movement needed for a full screen rotation. It normalizes everything — DPI, sensitivity, game engine, and mousepad size:

• Low sensitivity: 50–80 cm/360 (large mousepad, precise tracking)
• Medium: 30–50 cm/360 (standard desk space, balanced aim)
• High: 15–30 cm/360 (fast flicks, smaller mousepad)

A 40 cm/360 sensitivity means you move your mouse 40 cm on the pad to complete one full rotation — regardless of which game you play. Use our Mouse Sensitivity Converter to find your cm/360 and transfer it between games.

How to Find Your Ideal Sensitivity

1. Start medium: Set your mouse to 800 DPI and pick a mid-range in-game sensitivity for your game.
2. The PSA method: In the practice range, place your crosshair on a static target at medium distance. Strafe left and right while keeping your crosshair locked on the target. If you over-correct, lower sensitivity. If you cannot keep up, raise it.
3. Fine-tune in 0.01 increments: Change sensitivity by 0.01 at a time (not 0.05 or 0.10) until tracking feels effortless.
4. Commit for a week: Do not change sensitivity for at least 7 days. Muscle memory requires consistency.

Mouse Acceleration: Why You Should Disable It

Mouse acceleration (also called "enhanced pointer precision" in Windows) maps physical speed to cursor distance non-linearly. This means the same physical movement produces different cursor distances depending on how fast you moved. For gaming, this introduces inconsistency. Disable it in:

• Windows: Settings → Bluetooth & devices → Mouse → Additional mouse settings → uncheck "Enhance pointer precision"
• macOS: System Settings → Mouse → uncheck "Natural scrolling" and set tracking speed manually
• In-game: Most competitive games disable it by default. Verify in settings.

1% Low FPS and Input Lag

Sensitivity is only half the equation. If your game stutters (low 1% FPS), your aim suffers regardless of eDPI. A stable frame rate matching your monitor's refresh rate ensures the most responsive input. Use our FPS & Refresh Rate Calculator to understand the relationship between frame time and input latency.

Field of View (FOV) and Sensitivity

FOV affects perceived sensitivity. A higher FOV makes targets appear smaller and further away, which can make your sensitivity feel faster. Most competitive players use vertical FOV 90–110°. Our FOV Calculator converts between horizontal, vertical, and diagonal FOV across different aspect ratios.
